I was doing a slip with three layers, but stopped because it was messy and I couldn't it tight without rolling the elastic. The last one I did I used a square knot with just one layer...it was much neater and a ton puffier!! (is puffier a word?!?! ...lol) Anyway, on my thread from the other day, another HG posted a link to a video she did of a slip with one layer. I am going to try it since it is different from what I was doing with my slip.
